The sap as tapping products from the fruit of arenga pinnata
palm has high sugar contents and very sweet taste with colorless
liquid. Thus the arenga pinnata can be use as feedstock for
alcohol fermentation. The sap is collected by cutting the fruit at
its point of attachment to the stalk. During this tapping process,
this fruit secrete the sap. It’s almost colorless and has very sweet
taste. From six different palm samples were analyzed in the
Philippines, the best quality of the sap in grams per 100 cubic
centimeters containing 18.00 total solid, 17.00 sucrose, 0,48
ashes, and trace of reducing sugars. The alcohol production from
nypa palm sap should be above 6% of the sap. In favorable
condition it would be 7%. It seen that 9,300 gallons of the sap
would produce about 650 gallons of alcohol, which would be the
annual yield per acre [Anonimous,2007, Gibbs,1911].
